We are now using our own hosting that we have setup, with expert help from a joomlapolitan friend and a few suppliers, as a redundant high-availibility high-security virtual cluster this summer, and optimized it to run CB super-fast.
And as a result, there is plenty of free capacity...
If there is enough interest we might do something.
It wouldn't be the cheapest in town, but until now has proven to be rocking fast and reliable.
Anybody interested to be hosted on this same HA HS cluster ?
